Mike Trivisonno (1947-2021) *74

was an American radio broadcaster, known for hosting his own self-titled afternoon talk show on Cleveland radio station WTAM AM 1100. He was widely referred to simply as "Triv" by callers and the Cleveland media. He was a frequent caller on the Sportsline radio show on WTAM AM 1100,(during this period the station was operating under the WWWE call letters). The show was hosted by the acerbic Pete Franklin and dealt with Cleveland sports. Franklin, who would typically cut off most callers, began giving "Mike from Mayfield" some latitude due to knowledgeable commentary, particularly regarding the Cleveland Browns. Franklin began mockingly referring to Trivisonno as "Mr. Know It All," a moniker he would carry into his own radio career.

Trivisonno eventually began his own broadcasting career in 1987, working for a time at WNCX, commenting on sports (particularly boxing) and becoming a full-time personality from 1989–1992.
